The Lowdown
Alright, let’s talk about Jaconé in feet and Fahrenheit. The first real swell comes Monday morning, September 7th. We’re looking at 8ft of south swell, 11-second period, and the water is glassy. That’s excellent surf, but it’s for the experienced crew only. Water temp is about 72°, which is normal for this time of year. The combined energy is strong at 1549. Monday afternoon is also good, with 8ft from the SSW and still glassy.
Tuesday the 8th holds up with 5ft south swell in the morning, clean with offshore wind. The energy is 902. The afternoon is a bit smaller at 5ft, but still clean. The break is exposed to the SE, so it’s matching the swell direction well. Crowds are “sometimes,” so you might see a few others.
Wednesday the 9th through Saturday the 12th is a rough patch. Swell drops to 4ft and smaller, the wind gets messy, and the energy falls off. Thursday has a 4ft south swell with a 13-second period, which gives it some shape, but it’s tiny. Saturday morning is a washout with onshore wind and only 4ft; the afternoon is glassy but only 2ft.
Sunday the 13th is flat and poor.
Monday the 14th brings a rebound: 6ft from the south, clean with offshore wind, and energy at 787. A solid session.
The real standout is the weekend of the 20th. Saturday the 19th has 5ft south swell, 12-second period, and light clean wind. Energy is 639. The absolute best is Sunday the 20th. Morning: 5ft south swell, a very long 15-second period, glassy conditions, and energy of 1138. That’s strong. The afternoon is also excellent, 5ft, 14-second period, and clean cross-off wind. This is groundswell, so at a beach break it might break a little straight, but with the size moderate and the wind clean, it’ll be well worth it. This is the highlight of the whole outlook.
Monday the 21st drops off again, so don’t sleep on it.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
